To avoid a lot of if statements in the code create a struct rvin_info to store this information. While we are at it rename the poorly chosen enum which contains the different model IDs from chip_id to model_id. Also sort the compatible string entries and make use of of_device_get_match_data() which will always work as the driver is DT only, so there's always a valid match.
